Cov khoom
HPMA yog ib qho hnyav molecular polymeride, nrog qhov nruab nrab molecular hnyav 400-800. Tsis muaj tshuaj lom, soluble hauv dej, tshuaj lom neeg thiab thermal stability, decomposed kub siab tshaj 330 degree. HPMA muaj qhov pom tseeb qhov pib tshwm sim nyob rau hauv qhov kub siab (350 degree) thiab siab pH (8.3) qib, tsim nyog siv rau hauv cov dej alkaline lossis tsim nrog cov neeg ua haujlwm. Nws muaj cov nplai zoo inhibition tiv thaiv carbonate thiab phosphate nplai nyob rau hauv qhov kub thiab txias 300℃nrog lub sijhawm ua haujlwm ntev li 100 teev. Vim nws qhov zoo scale inhibition thiab siab kub kam rau siab, HPMA yog dav siv nyob rau hauv desalination cog ntawm flash vaporization khoom, tsis tshua muaj siab boiler, chav locomotive, crude roj evaporation, roj av pipeline, thiab industrial circulating dej txias systems. Tsis tas li ntawd, HPMA muaj kev tiv thaiv corrosion zoo thaum siv ua ke nrog zinc ntsev. HPMA kuj tseem siv tau los ua cov khoom ntxiv rau cov cement.

Kev siv
HPMA feem ntau yog siv ua ke nrog cov organic phosphonate ntawm ntau npaum li cas ntawm 1-15ppm rau circulating dej txias system, oilfield sau dej, crude roj dewatering thiab low-pressure boilers. HPMA muaj qhov zoo scale inhibition (98%) thiab scale stripping zog. Thaum siv ua ke nrog zinc ntsev, nws tuaj yeem cuam tshuam cov pa roj carbon steel corrosion.
